Explanation:
The order of boiling point depends upon the type of interactions present between the molecules.
Potassium fluoride (KF) is an ionic compound and the opposite ions are held together by strong electrostatic forces.
is a covalent compound and the molecules are held together by weak van der Waals' forces.
Formaldehyde is a polar compound due to presence of polar carbonyl group. Hence dipole-dipole force is present between formaldehyde molecules.
Thus the decreasing order of boiling point is:

The answer I got is Carbon hope this helps
Explanation:
Answer:
Tea is a solution of compounds in water, so it is not chemically pure.
Explanation:
It is usually separated from tea leaves by filtration. B Because the composition of the solution is uniform throughout, it is a homogeneous mixture.
The measurement with the highest weight has more matter.
We shall convert all expression to kg.
350g to kg = 0.350 kg
1 kg is equals 100000 cg
Then x kg is equals 3.5 * 104 cg.
Hence 3.5 * 10^4 cg = 0.35kg
Also 1 kg equals 10 hg
Then x kg equals 3.5 * 103
So x = 350 kg. Hence 3.5 * 103 hg is the answer
